- Ending the pull too early
- Hips rising more than shoulders
- Catching it with elbows down, then moving elbows up (on some of them, not all, and the fact that you’re even trying to catch them with elbows-up is a good thing)
To handle the first… the focus should be on lifting it as high and as fast as you can, not necessarily on catching it. This comes with experience and practice.
To handle the second… intentionally make the first pull slower. Don’t start REALLY accelerating until the bar clears your knees. Until that point, try to raise your hips and shoulders at the same rate, so that you keep the same relative angle with the ground. Then, once you get into hang-clean position, enter the second pull.
On the third… that’s just got to be instinct. Practice enough and you’ll develop the flexibility in your shoulders and wrists.
Added note: lifting on a flat surface and flat shoes adds safety.
And powercleaning 135 at a weight of 160 is not that bad.
